How to Integrate Go with Grafana Dashboards

Integrate Go with Grafana by exposing metrics via the runtime/pprof package and configuring Grafana to scrape the /debug/pprof endpoint.

import _ "net/http/pprof"

func main() {
    go func() {
        // Exposes /debug/pprof/profile, /debug/pprof/heap, etc.
        http.ListenAndServe("localhost:6060", nil)
    }()
    // Your application logic here
}

In Grafana, add a Prometheus data source pointing to your Go app's metrics endpoint, then create a dashboard panel querying the go_goroutines, go_memstats_alloc_bytes, or process_cpu_seconds_total metrics.

Go has a built-in tool that records how your program uses CPU and memory. You turn this tool on by adding a few lines of code, which makes your program share this data over the network. Grafana connects to your program, reads that data, and draws charts so you can see if your app is running smoothly or if it is using too much power.
